IRCDB: A Database of Inter-residues Contacts in Protein Chains

In protein structure prediction, identifying the inter-residue contacts is a very important task to understand the mechanism of complicated protein folding and therefore to predict three-dimensional structures of proteins. So far, many methods were developed to predict inter-residue contacts. However, no special database consisting of detailed inter-residue contacts for each PDB protein chain has been built. Our database of inter-residue contacts in protein chains consists of protein chains extracted from PDB database. For each protein chain, we analyzed its inter-residue contacts, classified it into one class, and obtained several groups of inter-residues contacts.
